-MEANS FOR SUPPORTING THE UPPER STORIES OF A BUILDING.

Application filed September 29, 1923. Serial No. 665,522.

To all whom it may concern:

Be it known that we, FREDERICK ZACH ARIAS and EMANUEL MANHEIMER, citizens of the United States, residing, respectively, at 2440 Valentine Avenue, New York city, in the county of Bronx and State of New York, and at 1133 Findley Avenue, New York city, in the county of Bronx and State of New York, have invented a new and'useful Improvement inMleans for Supporting the Upper Stories of a Building, of which the following is a specification.

The object of the invention is to provide means, of a permanent nature, for supporting the upper stories of a building, with-.

out shoring, when part, or all, of the wall of a lower story or stories is .to be removed;

This is accomplished by inserting struts through holes in the wall above the part to be removed and tying'parallel' beams to the endsv of these struts. The struts and beams are of steel, reinforced concrete or the like, and of suitable forms, and their dimensions are determined by the load to be held up. Then a portion of. the lower wall, where a column is to be placed, is ripped out. When this is done, the wall of the stories over the ripped-out section is carried by the supporting structure, which is carried by the wall itself. The column is then installed, in supporting relation to the supporting structure. After the column, or columns, have been put in, the balance of the wall to be removed is torn out.

This method obviates the use of the ordinary temporary shoring, consisting of wooden needles and spur bracings, and saves time and cost and the space taken up by such shoring. In the shoring method, it is necessary to install steel-work to hold the upper story walls, and to underpin, or fill in between the new steel work and the old walls, and when all this has been done it is then necessary to remove the wooden needles and fill in the openings which they leave. In the present method the struts and beams stay in place as part of the remodeled building and the columns are installed in direct supporting relation to this permanent supporting structure.

Increased safety is attained because the upper stories do not depend for their support on temporary wooden needles or spurs, but are supported throughout on permanent structure, which does not give the building a chance to settle.

In the accompanying drawings: Figure 1 is a front elevation of of the first story and a portion of the wall of the secondstory of a building, showing the permanent supporting structure in the wall '7 place, a part of the outer beam of the structure being broken away to showv some of the struts in section in holes through the wall.

Two columns have been installed in open wall, above the part to be removed, theline of'openin'gs extending across the front of the building. The holes may be at equal or unequal intervals, but are preferably more,

numerous or closer together in the solid parts of the wall, and fewer directly over. window or door openings. Struts 4 are inserted horizontally through these holes so as to project at both'front and back of the wall, and are made tight in-a suitable manner, a filling being indicated by cross-hatching at 5 in Fig. 3. The struts are made of, steel beams, angle-irons, plates, channels, or suitable combinations of forms, or mightbe' of reinforced concrete. To the projecting ends of the struts are next fastened, by bolts or rivets 6 a pair of heavy parallel horizontal beams or girders 7 spanning the lower wall region where work is to be done, these beams lying outside and inside of the wall lines, respectively. In this way an integral, permanent, supporting structure is produced.

A portion of the lower wall where a column is to be placed is then ripped out, leaving an opening, such as the gap 8, extending from the supporting structure down to the point where the base of the column is to rest. The gap may be as wide asmay be convenient, and the wall above the gap, before the column is put in, is amplyflsupported by the supporting structure 4, .6,

nice, not necessary to show.

mediate the ends there would be a bridging support.

A column 9, having a transverse cap 10, is put in position, the girders 6 resting sol idly on the ends of this can. As many gaps in the lower wall are made as there are to be columns. Another gap and another column are represented at S 9, toward the opposite end of the span. After the column or columns are in place the balance of the wallto be removed is taken out. In Fig. 1 this. includes all the first story wall below the horizontal supporting structure and between the columns.

In completing the job, the girder on the outside of the wall may be covered over by a galvanized iron or copper or concrete cor- In the illustrated case, in which the inside girder is substantially concealed between the first story ceiling and the second story floor, it is necessary to take up the flooring of the second floor adjacent the front wall and cut away the existing floor beams at this region, replacing them in a proper manner after the new steel-work is in place. Otherwise, the entire operation may be carried out under the first floor ceiling, depending upon the height of the first story and uponwhether the owner objects to the inner beam. showing at a substantial depth below the ceiling, the depth of the beams depending, of course, upon the load to be carried and upon the distance on centers between the supports of the beams.

What is claimed as new is:

1. The herein described method which comprises installing struts through the wall of a building at the top of a story to be removed and tying parallel beams to the ends of these struts, to form a permanent supporting structure'deriving its support from the wall itself for support of the upper stories, and then tearing out a part of the lowerwall, substantially as set forth.

2. The herein described method which comprises installing struts through the wall of a building at the top of a story to be removed and tying parallel beams to the ends of these struts, to form a permanent supporting structure deriving its support from the wall itself for support of the upper stories, then tearing out a portion of the lower wall and installing a permanent col umn in the opening of the wall in supporting relation to said supporting structure. 7

8. The herein described method which comprises installing struts through the wall of a building at the top of a story to be removed and tying parallel beams to the ends of these struts, to form a permanent supporting structure deriving its support from the wall itself for support of the upper stories, then tearing out portions of the lower wall and installing permanent columns in the openings thus formed in supporting relation to said supporting structure, and finally tearing out the balance of the wall to be removed.

4. The herein described permanent sup porting structure for holding up the upper stories of a building without shoring, comprising struts inserted through openings in the wall above a story to be torn out and parallel beams tied to the ends of said struts, the said structure deriving its support from the wall itself for support of the upper stories while a partof the lower Wall is torn out.
